Making my inside lab an outside dog

My wife has dropped the hammer since we are on the way with baby #2, that my 110# lab has to now live outside. She is tired of him shedding all the time even tho I trim him and have one of those automatic Roomba things sweeping daily. I kind of understand but that's still my boy we are talking about. I agreed and decided to bury an elect fence, I have this obsession of my dog only being in my yard, not tearing other peoples shite up. What are some ways to break it to him slowly so im just not throwing him out there. He stays out there most of the day, just he knows he sleeps inside at night. I have a small shed I can put his bed in, just know he will go ape shite the first couple of nights.
